The correct answer is A. Farm mechanization resulted in an increase in farm production.
The mechanization of agriculture describes the development process mainly of cereal cropping and livestock farming, during which production and economic methods radically changed between the end of the 19th and the second half of the 20th century. This development has had a tremendous impact on the labor market and on the population development of rural and urban areas, as the number of inhabitants in the rural villages has steadily increased, while at the same time it has been rapidly increasing in the cities. As a result of mechanization, the total number of human and animal workers in agriculture has fallen dramatically, because even draft animals have hardly been used since the mid-20th century. It also increased the production in the farms, since the use of machinery instead of human work allowed the production of more goods per working days.
Best answer: B. Trade networks develop to exchange resources.
When one nation or region has resources that others do not, it can use those resources as a trade commodity to exchange with other nations. For instance, areas that have rich oil resources will export oil to countries that don't have oil reserves as a natural resource. In turn, those countries may have other commodities that they can exchange -- agricultural resources from countries with fertile agricultural land, for instance.
The US Constitution gives the legislative branch the power to make laws. This is an example separation of powers.
